Chapter 2 Using the NetFlow Collector User Interface
Configuration
BGP Attribute
A BGP Attribute key builder looks up a BGP attribute from the Cisco NetFlow Collector BGP peer
using an address from a flow. The complete AS path is a special case that uses both a source and a
destination address from a flow. The BGP Attribute key builder has the following attributes.
Attribute Description
Output name Column name in output; defaults to the field ID if
not specified.
Attribute type One of the following radio buttons:
• Complete AS Path
• Well Known Name—Select from ORIGIN,
AS_PATH, NEXT_HOP,
MULTI_EXIT_DESC, LOCAL_PREF,
ATOMIC_AGGREGATOR,
AGGREGATOR, COMMUNITY,
ORIGINATOR_ID, or CLUSTER_LIST
• Integer Type ID.
Source address key ID of a key builder that returns the source address
for a complete AS path look up, otherwise
disabled.
Destination address key ID of a key builder that returns the destination
address for querying the attribute.
Post-aggregation Determines whether look ups are performed for
each flow or at the end of the aggregation period;
this should always be selected, otherwise
attributes are queried from the Cisco NetFlow
Collector BGP peer as flows arrive resulting in a
significant performance impact.
